PATENT OFFICEo COPYING-BATH.

SPECIFICATION forming part of Letters Patent No. 788,787, dated May 2, 1905,

Application tiled March 10| 1904. Serial No. 197,539.

To all whom, it may concern:

Be it known that I, WILLIAM A. MURRAY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Copying-Baths, of which the following is a specification.

r1`his invention relates to co1i)ying-baths; and the primary object of the same is to provide a device of this class having a simplified construction and capable of holding a number of pads or cloths and also to contain suflieient moisture to dampen any number of pads or cloths and maintain the latter in condition for use for a considerable length of time.

A further object of the invention is to provide a copying-bath having a top portion or cover pivotally held therein and capable of being adjusted vertically as well as readily removed and applied with respect to the body of the bath.

A still further object of the invention is to so organize the several parts or elements of the bath that they will be rendered readily accessible, convenient in operation, strong, and durable, and including means for storing a great number of pads or cloths.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a longitudinai vertical section of a copying-bath embodying the features of the invention and showing the top portion or cover open. Fig. 2 is a similar view showing the top portion or cover closed. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 2. Fig. i is a detail perspective view of a part of the upper portion of the body.

Similar numerals of reference are employed to indicate corresponding parts in the several views. y

The numeral 1 designates a body of considerable depth and having a box or tank conguration and preferably constructed from noncorrosive metal. The body is provided with an upper open end, and therearound is formed a beaded rim 2 to strengthen the same and effect a neat and smooth finish. The bod y is divided by a horizontal partition 3, which is located near the bottom 4 to form a drawer or slide compartment 5, in which is arranged a drawer or slide 6, with opposite packed ends 7, formed by bending the terminals of the said drawer or slide upwardly and inwardly over wood strips 8, which give the drawer or slide ends suiiicient rigidity to maintain the said drawer in form and facilitate movement thereof into and out of the compartment 5. For convenience in operating the draweror slide 6 a knob or analogous pull device 9 is attached to the outer end thereof, and said drawer or slide is formed without sides, so that pads which are held between the ends 7 may be readily accessible and easily withdrawn from or disposed in the said drawer or slide. The bath is portable, and to facilitate movement thereof from one position to another grips 10 are secured to the upper portions ofthe ends of the body and in the present instance consist of rings, though other devices may be used. tition 3 is a moisture-absorbing pad 11., of plaster-of-paris, held in a metallic tray or pan 12, which is fixed to said partition. This pad 1 1 terminates a considerable distance from the rear end of the body 1, and the plaster-ofparis extends upwardly iiush with the upper edge of the pan-or tray. Near its rear end the opposite sides of the body are formed with vertical slots 13, communicating with outstanding upright tubular guides or barrels 14C, which are fully open at the top and closed at the bottom and which constitute covering means for the slots. These guides have their upper open ends surrounded by a strengthening-rim wire 15.

The top portion or cover of the bath consists of a metallic tray, pan, or shallow box 16, in which is secured a moistureabsorbing pad 17 of plaster-of-paris. ln view of the fact that the top portion or cover must be frequently moved under certain operations with respect to the pad 11 any tendency toward loosening or disintegration of the pad 17 must be obviated without in the least detracting from the absorbent characteristics of the material of which said pad is composed.

Arranged on the par- The preferred securing means shown consists of a series of metallic straps 18, extending longitudinally of the tray or pan 16 at a distance from the open side of the latter, which exposes the pad 17. Engaging the said straps 18 are cross or transverse straps 19, which are arranged alternately against opposite sides of the said straps 18. In the present instance three straps 18 and four straps 19 are used to form the securing means for the pad 17; but it will be understood that this number may be varied at will. The top portion or cover of the bath, as set forth, and clearly shown by Figs. 1, 2, and 3, has a pivotal or hinge movement in the body through the me- Vdium of a pintle or hinge-rod 20, extending transversely through the rear extremity thereof and continued beyond the opposite sides of the tray or pan 16 through the slots 13, the opposite portions of the pintle or rod engaging' the said slots being formed with fiat faces 21 to prevent wabbling or oscillation of the top portion or cover and also to facilitate the withdrawal and accurate disposition of the said top portion or cover in the body. The opposite extremities of the pintle or rod 2O are bent upwardly and extend through the central portion of the guides or barrels 14, said extremities being screw-threaded to provide adjusting-stems 22, which are engaged by upper adjusting-nuts 23, having milled heads 24, and lower bearing enlargements 25 formed with circumferential shoulders 26, which rest on the rims of the guides or barrels 14. The enlargements 25 also have depending extensions 27, which rotatably fit into the upper open ends of the guides or barrels and maintain the stems 22 in central relation in said guides.

From the foregoing it will be readily seen that the top portion or cover carrying the pad 17 may be quickly raised or lowered, or removed from and inserted in the body 1 without necessitating a disconnection of the nuts 23 from the stems 22 or a separation of the rod or pintle 20 from the top portion or cover. Moreover, the top portion or cover carrying the pad 17 may be vertically adjusted with respect to the pad 11 in accordance with the number of textile copying pads or cloths arranged between the two pads.

The use of the horizontal partition 3 also provides for the formation of a moisture-containing receptacle, a space being formed between the sides and front end of the tray or pan 12, and the adjacent walls of the body provide a water receiving space. Though plaster-of-paris has been described as the preferred material of which the pads 11 and 17 are composed, it will be understood that other materials or compositions may be adopted, if desired.

By forming the slots in the opposite sides of the body near the rear end of the latter and having said slots of considerable vertical extent the top portion or cover of the bath can be conveniently supported when open by resting against the upper edge or rim of the rear end of the body 1, as clearly shown by Fig. 1. By this means the said top portion or cover of the bath will always be in convenient position to readily close, and when open the weight strain of said cover is materially removed from the pintle or rod 20. By holding the cover or top portion when open in the body 1, as just set forth, projection thereof in an inconvenient manner materially beyond the confines of the body is prevented, and at the same time said cover is always within easy reaching distance. As a simple means for facilitating raising and lowering operations of the top portion or cover of the bath the free end of the latter is provided with a grip or ring 28. By forming the tray 12 of less dimensions than the body l and providing a space entirely around the said tray the excess moisture from the pad 11 is permitted to overiiow into said space and render the operation of the device more efective with respect to the cloth pads interposed between the plaster-of-paris pads 11 and 17. In preparing the copying-bath for use the pads 11 and 17 are moistened to prevent them from drying out and taking up the moisture from the cloth pads interposed therebetween too quickly.

The proportions and dimensions of the parts of the bath may be modified at will, and all the parts will be so joined as to obstruct the formation of leaking openings or apertures.
